2000 corvette remote start

The car has VATS, I bypass it. Even tested to make sure it is not the problem. I seems like the RPM are not programming properly.  And to answer few other questions, I would have gotten it done from a Professional, but noboy here wants to put remote start in a manual vette. I had done alarm before just not a remote start. This install consisted of G5 Solaris alarm, smart windows, Remote start. Everything else is working fine except for the remote start. Another thing I would like to point out is that only wires i hooked up are starter and ignition, other wires like heater, ignition 2, heater 2, AC I left along since my vette has that functionalty built in to keep everything on for additional 10 miuntes after the car is turned off.
